There's a similar scene in The Spectacular Now where Sutter Keely (played by Miles Teller) is having a soft, intimate conversation with Aimee Finecky (played by Shailene Woodley) and the camera ever so slowly draws closer to them. At first, you feel as if the gradual zoom-in is meant to make the relationship more intimate...but then you realize that it represents exactly how claustrophobic Sutter feels in that moment, beset on all sides by expectations imagined and very very real. This was my favorite moment in the whole movie.
The Spectacular Now is an unaffected movie, which is both its strength and weakness. It's a more honest portrayal of high school seniors than anything I ever saw back when I was that age. They're fumbling toward things certain and nebulous at the same time. Sutter and Aimee are uncertain in different ways. Sutter rides on the fumes of an alcoholic bravado, consistently destroying everything he could care about -- not in a bombastic, gaudy way, but in a quiet, muted subsiding that lets it happen. Aimee is quietly naive, loving and supporting for reasons pertaining more to her innocent self-conscious insecurity than any maturity.
